OBJECTIVE Our objective was to reveal the frequency and MDCT appearances of sternal variations and anomalies in subjects without sternal deformities. SUBJECTS AND METHODS One thousand consecutive patients who underwent thoracic MDCT examination were enrolled in the study. All MDCT data, including multiplanar and curved-planar reconstructed images, were(More)
Granulomatous mastitis (GM) is a rare inflammatory breast disease of unknown etiology. Although it usually presents with sinus formation and abscesses, it may mimic the clinical characteristics of breast cancer. The aim of this study was to identify the clinical, radiologic, and pathologic characteristics of patients with GM and to show the results of(More)
PURPOSE The aim of this study was to evaluate the effect of breast magnetic resonance imaging (MRI) on preoperative or intraoperative surgical planning. METHODS One hundred and sixty females with breast cancer were enrolled in the study. The contribution of MRI compared to MMG and USG, their histopathological concordance, and their impact on surgical(More)
A fully automated software is introduced to facilitate MR mammography (MRM) examinations and overcome subjectiveness in diagnosis using normalized maximum intensity-time ratio (nMITR) maps. These maps inherently suppress enhancements due to normal parenchyma and blood vessels that surround lesions and have natural tolerance to small field inhomogeneities(More)
RATIONALE AND OBJECTIVES The objective of this work was to develop a quantitative method for improving lesion detection in dynamic contrast-enhanced magnetic resonance mammography (DCEMRM). For this purpose, we segmented and analyzed suspicious regions according to their contrast enhancement dynamics, generated a normalized maximum intensity-time ratio(More)
OBJECTIVES Primary hyperparathyroidism (pHPT) is a common endocrine disease. The aim of this study was to assess the effect of the presence of thyroid nodules, adenoma weight, and ectopic localization on the sensitivity of different imaging studies in patients with hyperparathyroidism. STUDY DESIGN A series of 125 patients with pHPT who underwent(More)
A novel fully automated system is introduced to facilitate lesion detection in dynamic contrast-enhanced, magnetic resonance mammography (DCE-MRM). The system extracts breast regions from pre-contrast images using a cellular neural network, generates normalized maximum intensity-time ratio (nMITR) maps and performs 3D template matching with three layers of(More)
BACKGROUND Elective surgery for liver hemangiomas is still controversial. HYPOTHESIS Long-term results show that elective surgery for liver hemangiomas is safe and effective. SETTING A tertiary care university hospital in Istanbul, Turkey. PATIENTS Forty-two patients underwent surgery for liver hemangiomas between January 1988 and December 1998; 41(More)
Diagnosis of extrapulmonary tuberculosis is often difficult. Although positive chest radiographic findings or a positive tuberculin skin test supports the diagnosis, negative results do not exclude extrapulmonary tuberculosis. However, recognition and understanding of the radiologic findings of extrapulmonary tuberculosis can help in diagnosis. The spine is(More)
Thalassemia is a kind of chronic, inherited, microcytic anemia characterized by defective hemoglobin synthesis and ineffective erythropoiesis. In all thalassemias clinical features that result from anemia, transfusional, and absorptive iron overload are similar but vary in severity. The radiographic features of beta-thalassemia are due in large part to(More)
